Dr. Danny Cohen
Distinguished Engineer
CTO, Sun MicrosystemsTitle: Internet 0 (i0)Abstract: The growing demand for networking embedded devices has been met by a proliferation of incompatible standards that are repeating many of the early mistakes of what became the Internet. What's needed are the original architectural insights of the Internet, rather than their current technological embodiments. This is being done in the Internet 0
(i0) initiative. Just as the Internet introduced internetworking by carrying an IP packet end-to-end, i0 introduces interdevice internetworking by carrying modulation end-to-end. This is done by representing an IP packet in time-domain impulses, self-consistently timed to allow the transient response to settle over the size of the network. i0 addresses the most important performance constraint on providing smart infrastructure for homes, buildings, and factories: the cost of complexity. By bringing IP to the leaf nodes of a network, over any available physical transport, and in a way that is independent of network topology, i0 extends the Internet to the scale required by the trillion-dollar-per-year construction industry. Like the Internet protocol itself, i0 is not optimal for anything but good enough for just about everything.Bio: Danny Cohen is a Distinguished Engineer working on the HPCS Program. Cohen received his PhD from Ivan Sutherland at Harvard University.
Cohen pioneered visual realtime interactive flight simulation on general purpose computers. Later, he lead projects that pioneered realtime interactive applications over the ARPAnet and the Internet, such as visual flight simulation, packet-voice (aka Voice over IP) and packet-video.
After being on the computer science faculty at Harvard (1969-1973) he joined USC/ISI (1973-1993) where he started many network related projects, including Packet-Voice, Packet-Video, Internet Concepts, MOSIS, FastXchange (e-Commerce), Digital Library, and ATOMIC which was the forerunner of Myrinet. In 1993 he started working on Distributed Interactive Simulation through several projects funded by DoD. In 1994 he cofounded Myricom (with Chuck Seitz et al) which commercialized Myrinet, a high-performance system area network. In 2001 he joined Sun and is working there on optical interconnection.
Cohen served on several panels and boards for DoD, NIH, and NRC, including 5 years on the Scientific Advisory Board of the Air Force. He is a bona fide member of the Flat Earth Society, and a commercial pilot with SEL/MEL/SES ratings.
Danny is still a student of Ivan.Hosted by Gerard MedioniSnacks to be served.
